The Salt Marshes: Then and Now

Approximately 85% of San Francisco Bay’s wetlands have disappeared over the last 200 years due to industry and development, impacting the wildlife that lived in and around them. Some of the plants and animals have made a comeback. Learn the history of the salt marshes and the species affected by the changes. The presentation includes a slide show followed by an optional walk (approximately 45 minutes, weather permitting) to view a salt marsh and the remains of a salt evaporation pond.
